What does Q 2 represent in Hardy Weinberg?

What does the Q variable represent in the Hardy-Weinberg equation?

In this equation, p² is the predicted frequency of homozygous dominant (AA) people in a population, 2pq is the predicted frequency of heterozygous (Aa) people, and q² is the predicted frequency of homozygous recessive (aa) ones.

How do you find q in Hardy-Weinberg?

To find q, simply take the square root of 0.09 to get 0.3. Since p = 1 – 0.3, then p must equal 0.7. 2pq = 2 (0.7 x 0.3) = 0.42 = 42% of the population are heterozygotes (carriers).

What do PQ p2 2pq and q2 represent?

p2 +2pq + q2 = 1 Where p2 represents the frequency of the homozygous dominant genotype, q2 represents the frequency of the recessive genotype and 2pq is the frequency of the heterozygous genotype.

What does the 2 in 2pq mean?

In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.

What does the Q represent in the Hardy-Weinberg equation quizlet?

According to the Hardy-Weinberg equation, what does ‘q’ represent? Frequency of the recessive allele.

What do p and q represent in the Hardy-Weinberg equilibrium equation?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. … where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population.

Is P or Q recessive?

In the simplest system, with two alleles of the same locus (e.g. A,a), we use the symbol p to represent the frequency of the dominant allele within the population, and q for the frequency of the recessive allele.
